Key Highlights:
- The operation, named Operation Midnight Hammer, was led by US Central Command (CENTCOM).
- The B-2 Spirit stealth bombers dropped GBU-57 Massive Ordnance Penetrator (MOP) bombs on Fordow, a facility buried deep inside a mountain.
- The first operational use of MOPs, each weighing 30,000 lbs, was recorded during this mission.
- A US submarine also launched over two dozen Tomahawk cruise missiles on Isfahan.
- Over 75 precision-guided munitions were used in total.
Why Bunker Busters?
- Fordow enrichment site is buried 80–90 metres underground, designed to withstand conventional airstrikes.
- The GBU-57 MOP can penetrate up to 200 feet underground or 25 feet of 10,000 psi concrete.
- Only the B-2 Spirit can carry these bombs, capable of stealthy, long-range missions.
About B-2 Spirit Bomber:
